TPS92612QDBVRQ1 PMIC - Dalaivala wa LED Kutulutsa kofananira kwa PWM dimming 150mA sot-23-5 TPS92612QDBVRQ1 Mtundu watsopano weniweni

I. Chip ndi chiyani

Chip, chomwe chimatchedwanso microcircuit, microchip, or integrated circuit (IC), ndi silicon chip yomwe imakhala ndi dera lophatikizika, nthawi zambiri laling'ono kukula kwake ndipo nthawi zambiri limakhala mbali ya kompyuta kapena chipangizo china chamagetsi.

Chip ndi liwu lodziwika bwino la semiconductor component product, chonyamulira chozungulira chophatikizika, chomwe chimapangidwa ndi zopyapyala.

Wafer ndi kachidutswa kakang'ono kwambiri ka silicon komwe kamakhala ndi gawo lophatikizika lomwe ndi gawo la kompyuta kapena chipangizo china chamagetsi.

II.Kodi semiconductor ndi chiyani

Semiconductor ndi chinthu chokhala ndi ma conductive pakati pa kondakitala ndi insulator kutentha kutentha.Mwachitsanzo, diode ndi chipangizo chopangidwa kuchokera ku semiconductor.Semiconductor ndi chinthu chomwe magetsi ake amatha kuwongoleredwa ndipo amatha kuchoka pa insulator kupita ku conductor.

Kufunika kwa ma semiconductors ndikokulirapo, pankhani yaukadaulo komanso chitukuko chachuma.Zambiri mwazinthu zamakono zamakono, monga makompyuta, mafoni a m'manja, ndi zojambulira za digito, zimakhala ndi mayunitsi awo ogwirizana kwambiri ndi ma semiconductors.

Zida zodziwika bwino za semiconductor zimaphatikizapo silicon, germanium, ndi gallium arsenide, ndi silicon yomwe imakhala yothandiza kwambiri pazamalonda pamitundu yosiyanasiyana ya semiconductor.

Zinthu zimakhalapo m'njira zosiyanasiyana - zolimba, zamadzimadzi, gasi, madzi a m'magazi, ndi zina zotero. Nthawi zambiri timatchula zinthu zopanda mphamvu zamagetsi, monga malasha, makhiristo ochita kupanga, amber, ndi zoumba, monga zotetezera.

Ndipo zitsulo zokhala ndi ma conductive monga golide, siliva, mkuwa, chitsulo, tini, aluminiyamu, ndi zina zotere zimatchedwa kondakitala.Zida zomwe zimagwera pakati pa ma conductor ndi insulators zitha kutchedwa semiconductors.

III.Kodi dera lophatikizidwa ndi chiyani

Dongosolo lophatikizika (IC) ndi kachipangizo kakang'ono kamagetsi kapena kagawo kakang'ono.

Pogwiritsa ntchito njira inayake, ma transistors, resistors, capacitors, ndi ma inductors omwe amafunikira pozungulira ndi mawaya amalumikizidwa palimodzi, opangidwa mu kachidutswa kakang'ono kapena tinthu tating'ono tating'ono tating'onoting'ono ta semiconductor kapena ma dielectric substrates, kenako ndikukutidwa mu chipolopolo cha chubu, kukhala microstructure ndi ntchito yozungulira yofunikira.

Zigawo zonse zomwe zili mmenemo zimapangidwira mwadongosolo, kupanga zipangizo zamagetsi kukhala sitepe yaikulu yopita ku miniaturization, kugwiritsa ntchito mphamvu zochepa, nzeru, ndi kudalirika kwakukulu.Imayimiridwa mudera ndi zilembo "IC".

Oyambitsa mabwalo ophatikizika anali Jack Kilby (mabwalo ophatikizika otengera germanium (Ge)) ndi Robert Noyes (mabwalo ophatikizika otengera silicon (Si)).Zambiri zomwe zimagwiritsidwa ntchito pamakampani a semiconductor masiku ano ndi mabwalo ophatikizika a silicon.

Dera lophatikizidwa ndi mtundu watsopano wa chipangizo cha semiconductor chomwe chinapangidwa kumapeto kwa zaka za m'ma 1950 ndi 1960.

Ndi njira yopangira semiconductor monga oxidation, photolithography, diffusion, epitaxy, ndi evaporation ya aluminiyamu, yomwe imagwirizanitsa ma semiconductors, resistors, capacitors, ndi zigawo zina zofunika kupanga dera ndi ntchito zina ndi mawaya ogwirizanitsa pakati pawo onse pa kachidutswa kakang'ono ka silicon, kenaka kukulunga ndi kukulungidwa mu chubu nyumba ya zipangizo zamagetsi.Pali mitundu yosiyanasiyana yazonyamula zipolopolo monga zipolopolo zozungulira, zosalala kapena zopindika ziwiri.

Integrated dera luso zikuphatikizapo Chip kupanga luso ndi luso kapangidwe, makamaka mu processing zipangizo, processing luso, ma CD ndi kuyezetsa, kupanga misa, ndi luso kupanga luso.
